Hi everyone,

I’m trying to figure out whether my FiiO K3 is the original/old version or the New K3 / K3 2021 version.

I bought it refurbished, and the invoice says “FiiO K3 2021 Refurbished.” However, the box and the device itself only say “K3” / “FiiO K3 Refurbished.”

The barcode on my box is:

6953175710165

From what I found online, this barcode appears to correspond to the original FiiO K3, while the New K3 / K3 2021 version appears to use:

6953175710202

I understand that the main internal difference is supposed to be:

Old/original K3: AKM AK4452 DAC

New K3 / K3 2021: ESS ES9038Q2M DAC

The issue is that Windows only shows it as K3, and the label on the unit itself only says Model: K3. I do not see “New K3,” “K3 2021,” “ES9038Q2M,” or “AK4452” anywhere on the device.

Is there any reliable way to confirm which version I actually have without opening the unit?

Can the barcode, authenticity code, firmware revision, USB device ID, or anything in Windows/FiiO control panel prove whether it is the old K3 or the New K3?

I’d appreciate any help from people who own either version or know how to identify them.

Hi everyone,

I bought a refurbished FiiO K3 that was sold/invoiced to me as “FiiO K3 2021 Refurbished.” However, I’m trying to confirm whether the actual unit is really the New K3 / K3 2021, or if it is the original/old K3.

The box and the device itself both only say “K3” / “FiiO K3 Refurbished.”

The barcode on my box is: 6953175710165.

From what I found online, the original K3 may use barcode 6953175710165, while the New K3 / 2021 version may use barcode 6953175710202 (although not 100% sure about this). I also understand that the main internal difference is:

- Old/original K3: AKM AK4452 DAC

- New K3 / K3 2021: ESS ES9038Q2M DAC

The problem is that Windows only shows it as K3, and the label on the device itself only says Model: K3, not “New K3,” “K3 2021,” “ES9038Q2M,” or “AK4452.”

Is there any reliable way to confirm which version I actually have without opening the device?

Can the barcode, authenticity code, firmware revision, USB device ID, or anything in Windows/FiiO control panel prove whether it is the old K3 or the New K3?

I’d appreciate any help!
